%X The purpose of this laboratory study was to formulate graphene oxide (GO) nano-sheets and characterize composites of homogenously dispersed GO sheets in poly(methyl methacrylate) (PMMA) acrylic resin of two groups, i.e., with 0.025£¿wt/wt.% GO (GO1-group) and 0.05£¿wt/wt.% GO (GO2-group). A large array of surface, mechanical and dynamic mechanical properties, including creep, recovery, stress relaxation behaviour and temperature and frequency sweep of the formulated bone cements were further characterized. Analysis of variance test results (p£¿=£¿0.05, n£¿=£¿5) indicated that the nanohardness and elastic modulus of the experimental groups were not significantly different from those of the control. Micro-computed tomography results showed high porosity in the experimental groups. The compressive strength significantly increased both in GO1- and GO2-group under dry and wet storage conditions. The dynamic mechanical properties suggest a desirable role of GO in polymerization with PMMA. The produced GO-PMMA composites exhibited the expected characteristics, so their use in developing low-loading bone cement composites appears to be promising
